NOISELESS STEAM-NOZZLE.

SPECIFICATION forming' part of Letters Patent No. 291,762, dated January8,1884.

Application filed October 2, 1883. (No model.) I

To call 1072/0777, it may conccrn:

Be it known that I, OARLETON W. Nelson, of Montclair, in the county ofEssex and State of New Jersey, have invented a new and usefulImprovement in Noiselcss Steam-Nozzles, of which the following is afull, clear, and exact description.

The object of my invention is to provide a new and improyed steam-nozzlefor preventing steam that escapes under water from producing noises orthe so-called water-hammer.,7

The invention consists in a slotted tube surrounded by a perforatedcasing oontaining a packing of asbestus fiber, which fills the spacebetween the casing and the slotted tube, so that the steam must gothrough the asbestus fiber in passing into the water, whereby all noisesor water-hammer will be prevented.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a longitudinal section of my improved noiselesssteam-nozzle. Fig. 2 is a longitudinal sectional elevation of the same.Fig. 3 is a cross-sectional View, and Fig. 4: an end View of the same.

The tube A is provided with a series of longitudinal slots, a, thecombined area of which is greatly in excess of the cross-section of thetube. O11 one end of the tube a closed flanged cap, B, is screwed, andon the other end a fianged cap, O, provided with a central internally-screw-threadcd collar, c, is screwed. Between the two caps B O acylinder, D, is held, which is provided with a series of longitudinalslots, d, arranged as shown. A piece of asbestus cloth, E, is placedagainst the inner surface'of the cylinder D, and the space between theasbestus cloth or fabric and the tube A is filled with asbestus fiber F.The cap B closes one end of the tube A, and the other end is to beconnected with a tube for conducting steam from the boiler into thenozzle. The steam passes from the said conducting-tube into the tube Aof the nozzle through the slots a of the said tube A, through theasbestus fiber F and cloth E, and through the slots d in the cylinder D,and escapcs into the water iu numerous jets, whereby all noises areprevented.

Gravel has been used in steam-nozzlcs of the above-described kindheretofore, but the steam disintegrates and breaks the gravel in a Veryshort time. The asbestus fiber is not affected by heat, and as it isquite elastic it is not broken or disintegrated by the steam.

This nozzle is to be used for heating water or other liquids byinserting the nozzle in a bank and admitting steam into the bank througha pipe, on the end of which the nozzle is fastened.

Havin g thus described my inyention, I claim as new and desire to secureby Letters Patent- 1. vIn a steam-nozzle, a filling or packing ofasbestus, applied substantially as and for the purpose set forth.

2. A steamnozzle made substantially as herein shown and described, andconsisting of a slotted tube surrounded by asbestus fiber, and acylinder surrounding the latter, as set forth.

3. In a steam-nozzle, the combination, with the slotted tube A, of theasbestus fiber F, and the slotted cylinder D, substantially as hereinshown and described.

4. In a steam-nozzle, the combination, with the slotted tube A, of theasbestus fiber F, a slotted cylinder, D, and a layer of asbestus clothon the inner surface of the cylinder D, substantially as herein shownand described.

5. In a steam-nozzle, the combination, with a slotted tube, of a closedc-ap screwed on one end and closing the said end, a centrally-aperturedcap screwed on the other end, a cylinder held between the caps, andasbestus fiberfilled in between the slotted tube and the cylinders,substantially as herein shown and described.
